AUTOMATIC STEERING DEVICE FOR TORPEDOES.

SPECIFICATION forming part of Letters Patent No. 607,440, dated July 19,1898.

Application filed January 5, 1897. Serial No. 618,091. (No model.)

To all whom it may concern:

Be it known that I, EMIL KAs LoWsKY, a subject of the King of Prussia,German Emperor, and a resident of Berlin, in the Kingdom of Prussia,German Empire, have invented certain new and useful Improvements inAutomatic Steering Devices for Correcting Lateral Deviations ofFish-Torpedoes, of which the following is an exact specification.

This invention refers to torpedo-steering devices of the kind in whichis made use of a gyroscopic disk or wheel-2'. e., a disk or wheel thatis arranged in such a manner as to be able to rotate around its axisproper, as well as to revolvearound another axis lying rectangularly tosaid first-mentioned one. A disk or wheel arranged in such a mannertends to constantly maintain its plane of rotation, and the relativedisplacements of said wheel or disk and the torpedo occurring on thelatter getting deviated may well be and have been used forsuitablyoperating the rudder of the latter and causing the torpedo to be ledback into its proper straight path.

The success with which the steering devices referred to have met up tonow is a rather questionable one, especially what concerns torpedoeslaunched from a broadside-tube. The purpose of my invention, therefore,is to make said steering devices better suited for broadside-torpedoes,and I attain that object byarranging the gyroscopic disk or wheel insuch a way that the plane of rotation is vertical and is situated orstands parallel to the longitudinal axis of the torpedo. Besides thismain feature of my improved steering device other important featuresrelate to the means for driving the wheel or disk and to means foruncoupling the latter from said former means, as will all be fullydescribed hereinafter.

In order to make my invention more clear, I refer to the accompanyingdrawings, in which similar letters denote similar parts throughout thedifferent views, and in which Figure l is a vertical longitudinalsection through the middle portion of a fish-torpedo furnished with myimproved device. Fig. 2 is an upper View of the main parts of Fig. 1,some of said parts being in section and the shell of the torpedo beingleft away. Fig. 3 is a vertical cross-section through the middle portionof the torpedo. Fig. at is a separate vie'w of the driving anduncoupling device shown in the middle portion of Fig. 2. Fig. 5 is arear view of the mechanisms shown in Fig. 4. Fig. 6 is a rear View ofthe parts represented in the right-hand end of Fig. 2; and Fig. 7 is averticallongitud inal section through the middle portion and the rearportion of the torpedo, showing the connection between the steeringdevice and the rudder, this figure being drawn on a smaller scale.

Referring to Fig. 1, the shaft a of the gyroscopic wheel a is arrangedin the horizontal frame 0. The latter is carried by the vertical frame0, which is held by the frame 0 The frame 0 maybe rotated in the frame 0around a vertical axis. It is distinctly to be seen from Figs. 1 to 3that the plane of rotation of the wheel a stands parallel to thelongitudinal axis of the torpedo. During the time of its rest, as wellas during the time of being driven, the shaft a of the wheel CL isconnected with a shaft (1 Figs. 2 to 5, by means of a coupling t' t".The shaft 0. is arranged coaxially with the shaft a. The shaft a carriesthe movable part 2" of said coupling and may be lengthwise displaced andis provided with a cog-wheel it, which meshes with a rack 41. The latteris secured to a hollow cylinder 0?, arranged within and guided by acasing 61. A spring d situated within the cylinder (1, tends constantlyto move this latter (together with the rack a) outward or in thedirection of the cog-wheel n, respectively. In the position shown inFig. 1 said spring is strained or in its working position, respectively.The cylinder d is retained, however, by a pawl 0, and is kept retainedby said pawluntil the torpedo is launched. In the moment of launchingany suitable relieving device lifts the pawl 0 by the mediation of thelever 0 and the rod 0, and the rack '17. is then quickly moved alongbelow and together with the cog-wheel n. In consequence of the shaft aofthe disk a being connected withthe shaft a of the cog-wheel 7?. thequick rotation of this latter causes a quick rotation of said disk a.WVhen the rack n has finished its movement, a recess n Fig. 1, hasarrived below the cog-wheel n. The latter may thus turn free of the rackor the rack cannot impede the quick rotation of the disk a,respectively. The effect of the device or, more precisely, the degree ofeffect depends on the disk at being kept free of any impediment. Theshaft a with the cog-wheel it, forms also impediments after the disk athas been put into rotation. To uncouple said shaft from the shaft a,there is'provided a bell-crank lever 4", Figs. 2 and i, which may actwith an arm against a knob-like projection a arranged at an end of theshaft (1 Said action is effected by the corner or point 02 Fig. 1, ofthe rack or rod n pushing upon the other arm of said lever. The shaft ais thereby lengthwise displaced in such a direction that the two parts iz" of the coupling are disconnected, as shown in Figs. 4 and 5. Thisoccurs obviously instantly after the actuation of the disk a, which maythus freely rotate, as well as revolve. 1

When the torpedo deviates from its straight path, there occurs a turningof the disk a. relatively to the torpedo or, more precisely, a turningof the torpedo relatively to the disk a. An arm 0 projecting from theframe 0 and connected with the distributing device of a servi-motor,causes in consequence of said turning an actuation of the distributingslides or valves proper of said device. Said slides or valves arearranged within the easing 8, Figs. 1, 3, and 7. Servi-motors beingalready known to experts in the present time, I think I may abstain fromshowing and describing the details of such a motor, and I thereforeconfine myself to remarking that said motor is employed for operatingthe rudder 00 of the torpedo. and that it is driven by compressed air.The latter is contained within the reservoir 2 and is led to the motorby the pipe e. The piston-rod m of the motor operates the rudder by themediation of the shaft m and the rod m The shaft m is of course'providedwith crank-arms, as is also the lower end of the shaft of the rudder.

The piston-rod m is of course in any case displaced in such a directionthat the rudder (turned by this displacement in a correspondingdirection) deviates the torpedo back into its normal or straight path.Owing to the particular arrangement of the disk 0. and to freeing thelatter of all disturbing influences, the correction of the deviationtakes place with an accuracy never attained heretofore.

For the sake of completeness I finally remark that putting the spring dunder tension is effected by means of a movable arm w, Figs. 1 and 3,fixed to a shaft 10. The

latter is supported by brackets w projecting from the casing d. The freeend of the shaft w is formed into a prism to receive a key, asdistinctly shown in Fig. 3. It is further to be seen from this figurethat to keep the parts i 1 of the coupling in proper contact a springI), held by an arm 5 is provided. Said spring acts upon an arm or alever 17, which in its turn presses against the broadened end of theshaft a Having thus fully described the nature of this invention, what Idesire to secure by Letters Patent of the United States is 1. In afish-torpedo, having a gyroscopic disk or wheel, adapted to rotatearound a horizontal axis, and to revolve around a vertical one, andhaving said disk or wheel arranged so as to have its plane of rotationstand parallel to the longitudinal axis of the torpedo, the combinationwith the shaft of the said disk or Wheel, and with the driving devicefor the latter, of a coupling situated between the disk or wheel andsaid driving device, said shaft having a cog-wheel adapt ed to belongitudinally displaced, of a rack gearing with said cog-wheel, and ofmeans for longitudinally displacing said rack; and other means forautomatically disconnecting said coupling; said otherimeans beingadapted to be operated by the said rack, for the purpose as described.

2. In a fish-torpedo having a gyroscopic disk or wheel adapted to rotatearound a horizontal axis, and to revolve around a vertical one, andhaving said disk or wheel arranged so as to have its plane of rotationstand par-,

allel to the longitudinal axis of the torpedo, the combination with theshaft of the said disk or wheel, and with another shaft arrangedcoaxially with the said former one, of a coupling situated between saidtwo shafts; said coaxial shaft having a cog-wheel, and being adapted tobe longitudinally moved; a rack gearing with said cog-wheel, and meansfor longitudinally moving said rack; and a lever, adapted to be turnedby the said rack on the latter reaching the end of its path, and to movethe said other shaft so as to disconnect said coupling, for the purposeas described. In testimony whereof I have signed this specification inthe presence of two subscribing witnesses.
